How a balance transfer works in 60 seconds
You apply for a card that offers a 0% introductory APR on balance transfers. After approval, you tell the new issuer how much you want transferred and from which existing card. The new issuer pays off the old card directly (you never touch the cash). The balance now sits on the new card at 0% APR for the intro period (typically 18 to 21 months). You owe the new card, not the old one.
The old card is now empty. Do not put new charges on it; that is how people end up with double the debt.

Is the BT fee worth it?
Almost always, if your current APR is above 15 percent. The fee comes out of the savings, not on top of them.
| Balance | Typical fee (3% to 5%) | Interest avoided over 18 months at 22% |
|---|---|---|
| $3,000 | $90 to $150 | $167 to $250 |
| $5,000 | $150 to $250 | $278 to $417 |
| $10,000 | $300 to $500 | $556 to $834 |
Quick rules
The deadline matters
Most cards apply the 0% rate only to balances transferred within 60 to 120 days of opening the card. Initiate the transfer immediately on approval to maximise your runway and avoid missing the window.
Same-issuer restriction
You cannot transfer between cards from the same issuer. So a Chase Sapphire balance cannot move to a Chase Freedom Flex. Pick a new issuer.
Old card stays open
Keep the old card open after you transfer. Closing it reduces total available credit and can hurt your utilization ratio. Use it lightly each month to keep the issuer from closing it for inactivity.
Why some readers need both
Some cards offer different intro periods for purchases and balance transfers. If you have existing card debt AND an upcoming planned purchase, look for a card with strong terms on both. The Reflect Card and the Shield Runway Visa in our table both apply roughly the same long runway to both. The Citi Double Cash applies the long 0% only to BT, not purchases.
